Product description
KCL Ultra is made of glass wool slabs and rolls faced with durable glass fabric and KCL Ultra products have higher mechanics. Glass fabric installed in contact with the airstream, providing high acoustic absorption. The inside facing ensures a high acoustic absorption. Glass fabric facing constitutes a smooth surface, with high resistance to tearing (cleanable by brushing) with No fibers in airstream.
KCL Ultra range are manufactured from inorganic chemically biosoluble materials and do not include anything that would have effect on corrosion and shall not facilitate microbial growth.
Facings: KCL Ultra is faced with a black, strong, durable, dimensionally stable woven glass fabric.
Acoustical Performances
KCL Ultra is especially designed to provide exceptional sound absorption to acoustically sensitive environments and/or equipments as air-conditioning equipments, auditoriums, theatres, studios, acoustical building assemblies, curtain walls.
